Just acquired a 1947 Fisher 10 year Anniversary Model catalog and the FM broadcast dial is calibrated 200 - 300 for channels. I have never seen that before. Did other makers calibrate dials in FM Channels?

From https://en.wikipedia.org/wiki/FM_broadcasting_in_the_United_States
"In the United States, frequency-modulated broadcasting stations operate in a frequency band extending from 87.8 MHz to 108.0 MHz, for a total of 20.2 MHz. It is divided into 101 channels, each 0.2 MHz wide, designated "channel 200" through "channel 300". In actual practice, no one except the FCC uses these channel numbers; the frequencies are used instead. (Stations that broadcast on 87.7 MHz are in actuality licensed as television stations.)"

I've seen the channel numbers mostly in sets that have the old FM band----or both.

Interesting the Stromberg Carlson had both bands. Was there a transition period where FM broadcasters used both the old and new bands? No dial channels on my EH Scott 800B which I believe would have been a competitor to Fisher in '47. Must have been a marketing strategy that never gained acceptance.

My late-'50s Grundig-Majestic (made in Germany) has the channel numbers on the dial along with frequency.

My magnavox CR-192 FM tuner has both the channel markings and frequency.
